Description of the issue
I am testing the Omarchy manual installation described at: Manual installation but installing Omarchy on a partition (not using the entire disk) as described at: Manual Partitioning in archinstall for dual boot Omarchy. I tested on virtual machine before installing on real metal.
The proccess is:
- Install a base Arch system
- Run the Omarchy script
Despite the success reports, the installation crashed trying to install a base Arch system, after I configured everything as suggested:
- FAT32 partition mounted at /boot
- Btrfs partition with 4 subvolumes (@, @home, @log, @pkg)
- Btrfs partition encrypted using LUKS
The virtual machine disk mimics my real hardware hard disk and has other partitions:
- FAT32 (used with GRUB for dual booting existing Linux partitions)
- Swap partition
- Two existing Btrfs partitions (for other Arch Linux installations)
- Home partition formatted with EXT4
Virtual machine config:
